According to the statistics of the Ministry of public security, the annual loss of burglary in China is more than one trillion yuan. The annual loss of family caused by burglary is up to 1130 billion yuan. The safety of 467 million households' family property cannot be fully guaranteed. The safety has become the most urgent problem to be solved in individual family society. So why do burglaries in China not stop? The main reason is that more than 50% of Chinese families are still using class a locks. However, this kind of lock prevention technology and the ability to prevent violent opening are relatively weak. It takes only a few seconds for lawbreakers to open them easily. Video above. In addition, the police analysis pointed out that: most of the single buildings in the old villages in the city use a-lock, so they become a high incidence place of burglary cases, accounting for about 90% of burglary cases. And more than 70% of the burglary cases are 'door entry' through lock picking technology. It can be seen that the main sticking point of high incidence of burglary is that there is a huge hidden danger in the safety of locks. Therefore, it is necessary to install a safe lock. It's not safe to forget to bring the key to brew the lock for many window climbing and falling accidents. It just creates a chance for the lawbreakers to commit crimes. What they lose is their property. In recent years, forgetting to take the key has caused many tragedies and even paid the price of losing life. An 11-year-old boy who forgot his key and tried to turn the window from the balcony on the top of the building to go home accidentally fell down at around 18:00 p.m. on March 6, Chongqing Yubei Hongjin road. Although the boy is out of danger, he still needs to be observed and treated in intensive care unit. The boy in Chongqing is lucky, but Lianyungang is not so lucky. At about 9:00 p.m. on June 1, 2016, a man in a residential building in Jiangxiang, Haizhou District, Lianyungang, tried to climb back to the house through the window with the help of a rope because the key was locked in the house. Unfortunately, he fell from a high altitude and died after being rescued by a doctor. Similar tragedies happened in Xi'an. At 9 a.m. on June 21, 2016, Ms. Yin, from room 304, jinfuwan community, Shangnan County, Shaanxi Province, decided to climb in through the window because she didn't have the key. Unfortunately, she fell from the upstairs. When 120 arrived, Ms. Yin had no vital signs. There are so many cases and tragedies of this kind, but what makes tragedies is the little key we have to use every day. The high incidence of burglary is mainly due to the hidden danger of lock safety, while the main reason for the tragedy of entering the house by climbing the window is to forget the key. Therefore, it is the best choice to install a lock that is safe without a key. The intelligent lock has fingerprint password, key card, face APP and other opening methods, which is not only non reproducible, but also has the function of voice alarm and remote monitoring. Once someone tries to open the lock by technical violence, the intelligent lock will automatically alarm and monitor remotely, which will make the lawbreakers have no way to start, and the security is much higher than the mechanical lock. Spend thousands of yuan to buy a smart lock that has been used for five or six years or even more than ten years to protect not only the safety of property, but also the safety of family members.
